GUARDS at TV's top secret Space Cadets base can expecta rocket after a People investigator strolled around unchallenged this week.

Bosses at the £5million C4 reality show have made security their top priority.

Their elaborate plan to fool volunteers into thinking they they are blasting into orbit from a Russian space HQ relies on total secrecy. They even boast a team of guards are on hand to clear litter from the site.

But when our man decided to boldly go to the mocked up space base in Suffolk, security had vanished into a black hole.

Using a borrowed pass, he posed as a white van man and drove in and out of the disused RAF airfield THREE TIMES.

No checks were made at any time as he strolled around, mingling with production crew.

The investigator even got into a former hangar holding a fake space shuttle. One teenage guard told him: "I haven't got a clue what to do. It's all a bit boring to be honest." Other security men offered our man TEA and cheerfully waved as he left.

An insider at the Bentwaters site said: "They've spent millions on this but the guards appear to be in a parallel universe.

"They're about as much use as the fake spaceship. Security is a joke and they have handed out far too many passes." The contestants already believe they have been flown to Russia for training. And in tomorrow night's show they will board the spacecraft, expecting to spend five days circling the earth.
